Additional Information about EIN
The Employer Identification Number (EIN) helps the IRS track businesses for tax reporting and payments. EINs are required for some businesses — and recommended for most.
The IRS assigns EINs to US business entities for identification purposes. EINs should not be used for non-tax purposes like auctions or lotteries. The first two digits used to indicate location but now refer to the IRS EIN source.
